Bombmaking materials, bloody clothes, surveillance equipment and Colorado prison documents were found in the 1991 Cadillac driven by the paroled convict suspected of having slain the state's corrections chief at his home a week ago, according to evidence made public Tuesday.

The suspect, Evan Ebel, died Thursday after a harrowing chase and gunfight with Texas authorities. Colorado authorities announced Monday that ballistics tests confirmed that the 9mm Smith & Wesson pistol Ebel fired in North Texas was also used in the March 19 killing of Tom Clements, who headed Colorado prisons.

A black backpack contained explosive materials, bombmaking instructions, handwritten directions and documents from the Colorado Department of Corrections, according to search-warrant inventory released in Wise County, Texas.

The "miscellaneous" bombmaking materials included "black powder," a "projectile" and "four cartridge cases," the Texas Department of Public Safety Crime Lab reported.

The court files do not specify the nature of the prison documents.

The 28-year-old Ebel had an extensive criminal record and was paroled in January after serving almost eight years for an armed carjacking and assault.

Colorado authorities believe that Ebel also murdered Denver Domino's Pizza delivery driver Nathan Leon, of Golden, Colo., two days earlier. The Denver Post reported that documents revealed that Texas investigators found a Domino's "heatwave" bag, along with a Domino's pizza box, shirt, visor and "apparent letters from Nate." Police also found a mask, duct tape and zip ties, in addition to bloody pants in a cooler in Cadillac's trunk.

Other evidence sent to the El Paso County Sheriff's Office and the Denver Police Department included a digital voice recorder and a surveillance-camera system.

Authorities say Ebel was a member of the 211 Crew, a white supremacist prison gang. They are investigating whether Ebel may have had accomplices or acted on orders from a prison gang leader to kill Clements because he transferred members to other facilities.

Gov. John Hickenlooper has increased security for several Colorado officials.

Also Tuesday, a Texas deputy spoke publicly for the first time since Ebel shot him during a traffic stop that sparked the 100-mph gunfight with police. The wild chase ended 24 minutes later in the next county when Ebel crashed and was shot in the head.

Montague County Sheriff's Deputy James Boyd said he pulled over the old black Cadillac with Colorado plates because something was "just not right." Ebel shot him three times - twice in the chest and once in the head. His protective vest stopped two bullets; the third grazed his forehead. He was released from the hospital Tuesday and moved to a rehabilitation facility to recover from a severe concussion.

"As soon as I approached the passenger's side, I stuck my head over. All I saw was a gun. At that point in time, I remember seeing the gun shoot off a number amount of times, and I could see the cartridges fly out. At which point I blacked out and had no clue whether I was standing, sitting, whatever," the 27-year-old Boyd told the Fort Worth Star-Telegram in a hospital interview.
